Theory before practice

Paradoxically, for an experimental physics centre, one of the first fully operating research groups created for CERN was the Theory Division. In the early years, the Theory Division represented the only scientific activity of CERN - and it was the main item in the CERN budget!
The group was founded in May 1952 around Niels Bohr (seen here in the centre), one of CERN's founders, and was hosted by the Institute of Theoretical Physics in Copenhagen. In October 1957, the Council decided to terminate the agreement with Copenhagen and the Theory Division joined the laboratory in Geneva.
